Preheat oven to 180 degrees C. Place all vegetables, garlic and onion in a medium sized baking tray. Drizzle with olive oil, sprinkle with thyme and roast till tender, about 30-40 minutes.
In batches, blend roasted vegetables, chicken stock and pepper. Add additional stock as needed to reach desired consistency. Stir all batches of blended soup together in a bowl and serve immediately topped with a tablespoon of sour cream.
Yum- I roasted large wedges of ironbark pumpkin with the skin on, then the skin peels off so easily when cool. I also added bacon and ground coriander seeds. Makes the house smell very welcoming too.Thank you! - 23 Jun 2011
